  • the UE notifies a cellular access device, such as a base station, of its Media Access Control (MAC) address in the WLAN.
  • the base station matches the identifier of the UE in the cellular network, for example, the Cell-Radio Network Temporary Identifier (C-RNTI) and the MAC address, and then the UE corresponding to the C-RNTI has uplink data.

  • MAC address For another example, the UE notifies the WLAN AP of its identity in the cellular network, such as the C-RNTI. The base station notifies the WLAN AP that the UE corresponding to a C-RNTI has uplink data to be transmitted in the WLAN, and the WLAN AP can find the MAC address corresponding to the UE according to the matching relationship. Or the AP notifies the base station of the matching relationship between the C-RNTI and the MAC address.
  • the base station may use the MAC address as the UE identifier to notify the WLAN AP that the UE has uplink data to be transmitted in the WLAN.
  • the AP and the cellular access device have acquired the matching relationship of the identifiers of the UEs in the two networks.
  • step 102 is performed to send second indication information to the UE, where the second indication information is used to instruct the UE to send uplink service data to the WLAN AP.
  • the WLAN AP may schedule the UE by using a mechanism similar to the Point Coordination Function (PCF) mechanism. Different from the PCF mechanism, it is not necessary to poll all the UEs, but only the UE with the offloading service can be polled, and the AP is prevented from polling the UE, and the UE has no pending data packets, so the channel utilization can be improved to improve the channel. The efficiency of scheduling.
  • PCF Point Coordination Function
  • the AP sends a polling frame (Poll) to the UE with the uplink service data, that is, the second indication information is sent to the UE, and the timer is started, and the timer length is the point coordination frame interval (English: Point Coordination Function Interframe) Space, referred to as: PIFS).
  • PIFS Point Coordination Function Interframe Space
  • the AP may also schedule the UE in the following manner: when the AP wants to schedule a UE with uplink service data, the AP may send the request (English: Request To Send; RTS) frame. And actively sending the Allow To Send (English: Clear To Send; CTS) frame to the UE, which may be the foregoing second indication information. After the other UEs are listening to the CTS, they will not contend for the channel during the Network Allocation Vector (NAV) indicated by the CTS. After the scheduled UE hears, an implementation may be that the uplink service data is sent directly after the Short Interframe Space (English: Short Interframe Space; SIFS).
  • SIFS Short Interframe Space
  • the AP may start a timer. If the AP finds that the channel is idle after the timer expires, the UE does not send uplink data temporarily, and then releases the resource allocated by the UE for sending the uplink service data. The next UE is then scheduled.
  • the timer size is PIFS or larger (for example, including DIFS+backoff time).
  • the UE determines that it does not send the RTS and receives the CTS, and considers the CTS frame as an error frame and discards. Since the UE has data to be transmitted, according to the normal CSMA/CA mechanism, the channel idle is first allocated as a distributed coordination function Interframe Space (DIFS), and then backoff is retired according to a certain rule. . If the channel is still idle after the end of the backoff, the UE directly transmits the data packet. Since the NAV carried in the CTS makes other UEs not contend for the channel, the contention channel can be guaranteed to be successful. Similarly, the AP can start the timer, and the timer length can be set to DIFS+backoff. If the timer does not receive the uplink data packet sent by the UE, the UE is considered to have no uplink data to be sent. The next UE is then scheduled.

  • PSMP Power Save Multi-Poll
  • step 102 after the AP sends the second indication information, the scheduling continues until the data volume of the pending data of the UE is estimated to be 0, or the timer does not receive the uplink data packet sent by the UE. At this point, it can be determined that the amount of data has been sent this time. Then, the UE can be no longer scheduled until the first indication information of the UE is received next time.
  • the UE When the AP schedules the UE, the UE transmits the to-be-transmitted data generated by the application or the uplink service data in the data buffer area by using a transmission manner in the WLAN network.
  • the AP For an AP, there are usually many UEs. In other words, one AP can schedule multiple UEs. Therefore, with the assistance of the cellular network access device, the AP can learn whether each UE has data to be sent, and even know the amount of data to be sent of each UE, so it can be based on whether there is data to be sent.
  • the method of the uplink service data transmission in the embodiment of the present application is more efficient than the CSMA/CA-based contention access mode in the prior art.
  • FIG. 2 is a flowchart of a method for uplink service data transmission on the cellular network access device side in the embodiment of the present application.

本实施例提供一种上行业务数据传输的方法，请参考图1所示，为本实施例中的上行业务数据传输的方法的流程图。该方法包括以下内容：
步骤101：WLAN AP(下文可能简称AP)接收蜂窝网接入设备发送的第一指示信息，第一指示信息用于指示WLAN AP蜂窝网接入设备所服务的UE在WLAN AP有要进行业务分流的上行业务数据；
步骤102：WLAN AP根据第一指示信息向UE发送第二指示信息，第二指示信息用于指示UE向WLAN AP发送上行业务数据。
其中，蜂窝网接入设备例如为蜂窝网中的基站。
在步骤101中，第一指示信息可以承载在蜂窝网接入设备和AP之间的任一通信消息中。
可选的，第一指示信息还包括要进行分流业务的上行业务数据的数据量。例如：数据量的大小为1000字节。
可选的，第一指示信息还用于通知WLAN AP所述UE的标识信息，所述标识信息用于WLAN AP识别所述UE。
需要说明的是，在蜂窝网和WLAN中，同一UE的标识可能是相同的， 例如：UE在蜂窝网和WLAN中具有全球统一标识，即用户身份模块(英文：Subscriber Identity Module；简称：SIM)卡上的国际移动用户识别码(英文：International Mobile Subscriber Identification Number；简称：IMSI)。
然而，同一UE的标识在不同的网络中可能不同，此时就需要在两个不同网络中将同一UE的标识进行匹配。在具体实施过程中，有很多可能的实现方式，例如：UE将其在WLAN中的媒体接入控制(英文：Media Access Control；简称：MAC)地址通知蜂窝网接入设备，例如基站。然后基站将UE在蜂窝网中的标识，例如小区-无线网络临时标识(英文：Cell Radio Network Temporary Identifier；简称：C-RNTI)和MAC地址进行匹配，之后当C-RNTI对应的UE有上行数据需要在WLAN中传输时，基站可以通知WLAN AP该C-RNTI对应的MAC地址作为所述UE标识。或者，基站将C-RNTI和MAC地址的匹配关系告知WLAN AP，在基站告诉AP某个C-RNTI对应的UE有上行数据需要在WLAN中传输，AP可以根据所述匹配关系找到该UE对应的MAC地址。再例如：UE将其在蜂窝网中的标识，例如C-RNTI通知WLAN AP。基站通知WLAN AP某个C-RNTI对应的UE有上行数据需要在WLAN中传输，WLAN AP可以根据所述匹配关系找到该UE对应的MAC地址。或者AP将C-RNTI和MAC地址的匹配关系通知基站。基站可以将MAC地址作为UE标识，通知WLAN AP该UE有上行数据需要在WLAN中传输。在下面的描述中，假设AP和蜂窝网接入设备已经获取UE在两个网络中的标识的匹配关系。
当在步骤101中接收到第一指示信息之后，那么就执行步骤102，向UE发送第二指示信息，第二指示信息用于指示UE向WLAN AP发送上行业务数据。
可选的，WLAN AP可以采用类似于点协调功能(英文：Point Coordination Function；简称：PCF)机制的机制调度UE。与PCF机制不同的是，不用轮询所有UE，而只要轮询有分流业务的UE即可，避免AP轮询UE，而该UE没有待发数据包，所以可以提高信道的利用率，以提高调度的效率。在PCF 机制中，AP向有上行业务数据的UE发送轮询帧(Poll)，即下发第二指示信息给该UE，同时启动定时器，定时器长度为点协调帧间隔(英文：Point Coordination Function Interframe space，简称：PIFS)。若该UE有上行数据待发送，则在等待短帧间隔(英文：Short Interframe Space，简称：SIFS)之后，将发送上行数据；反之，若AP等待PIFS之后，尚未收到该UE发送的上行数据，则认为该UE没有上行数据待发送，则继续轮询下一个UE。
可选的，AP还可以采用如下方式调度UE：当AP希望调度某个具有上行业务数据的UE时，AP可以在没有收到请求发送(英文：Request To Send；简称：RTS)帧的情况下，主动给该UE发送允许发送(英文：Clear To Send；简称：CTS)帧，可以是前述的第二指示信息。其他UE监听到CTS之后，会在CTS指示的网络分配矢量(英文：Network Allocation Vector,简称NAV)期间不竞争信道。而该被调度的UE听到后，一种实现方式可能是直接在短帧间隔(英文：Short Interframe Space；简称：SIFS)之后发送上行业务数据。
可选的，AP可以启动定时器，若AP在定时器超时之后，发现信道空闲，则该UE暂时没有待发上行数据，则释放为该UE发送该上行业务数据所分配的资源。接着调度下一个UE。例如定时器大小为PIFS或更大(例如包含DIFS+退避(backoff)时间)。
另一种实现方式可能是，UE判断其未发送RTS就收到CTS，认为该CTS帧为错误帧并丢弃。由于该UE有数据需要发送，所以按照正常的CSMA/CA机制，首先侦听信道空闲为分布协调功能帧间隔(英文：Distributed coordination function Interframe Space，简称：DIFS)，之后按照一定规律退避backoff一段时间。若退避结束后，信道仍为空闲，则所述UE直接发送数据包。由于CTS中携带的NAV使得其他UE都不竞争信道，因此可以保证竞争信道成功。同样，AP可以启动定时器，定时器长度可以设置为DIFS+backoff，若定时器超时而未收到UE发送的上行数据包，则认为该UE没有待发上行数据。接着调度下一个UE。
可选的，第一网络侧设备具体还可以采用混合协调功能(英文：Hybrid  Coordination Function；简称：HCF)的机制或节能多调度(英文：Power Save Multi-Poll；简称：PSMP)的机制对要进行业务分流的UE进行调度。
可选的，在步骤102中，AP发送第二指示信息后，调度一直持续直到预估该UE的待发数据的数据量为0，或者定时器超时未收到UE发送的上行数据包为止。此时可以确定本次的数据量已经发送完。接下来就可以不再调度该UE直至下次接收到该UE的第一指示信息。
当AP调度该UE时，该UE将应用产生的待发数据或者数据缓存区中的上行业务数据通过WLAN网络中的传输方式进行传输。
对于AP而言，UE通常有很多个。换言之，一个AP能够调度多个UE。因此，通过本实施的方法，在蜂窝网接入设备的辅助下，AP能够获知每个UE是否有待发数据，甚至还能够获知每个UE的待发数据量，所以就可以根据是否有待发数据和/或UE的待发数据量进行调度，相比于现有技术中基于CSMA/CA的竞争接入方式，本申请实施例中的上行业务数据传输的方法的效率更高。
接下来请再参考图2所示，为本申请实施例中蜂窝网接入设备侧的上行业务数据传输的方法的流程图。该方法包括以下内容：
步骤201：蜂窝网接入设备接收所述蜂窝网接入设备所服务的UE发送的通知信息，该通知信息用于通知蜂窝网接入设备所述UE要传输上行业务数据；
步骤202：蜂窝网接入设备根据通知信息确定所述UE是否有要进行业务分流的上行业务数据；
步骤203：如果有，蜂窝网接入设备向WLAN AP发送第一指示信息，第一指示信息用于指示WLAN AP所述UE在所述WLAN AP有要进行业务分流的上行业务数据和/或指示所述WLAN AP所述要进行业务分流的上行业务数据的数据量。
其中，在步骤201中，通知信息的具体实现有多种实施方式，例如新定义的通知信息。或者是调度请求(英文：Scheduling Request，简称：SR)；或 者是缓存状态报告(英文：Buffer Status Report，简称：BSR)或增加是否分流标识的BSR。
新定义的通知消息，例如仅包含UE标识；又例如包含UE标识，以及该UE所对应的待传数据量。其中待传数据量可以是具体的数值，例如1000bytes。也可以是待传数据量对应的级别，例如1000bytes对应级别5。又例如，包含UE标识，该UE所对应的待传数据量，以及是否分流的标识。若通知信息中，只包含UE标识，则认为所述UE有上行数据待分流到WLAN，但具体待发数据量未知。例如UE标识为MAC地址1，待传数据量为1000字节。例如UE标识为C-RNTI 1，待传数据量为1000字节。例如UE标识为MAC地址1，待传数据量为1000字节，是否分流的标识为是。若同时有多个UE的上行数据分流到WLAN中，则通知消息中仅包含UE标识列表，或者包含UE标识列表以及每个UE所对应的待传数据量。
接下来介绍通知信息为BSR的情况。或者是调度请求(英文：Scheduling Request，简称：SR)；或者是缓存状态报告(英文：Buffer Status Report，简称：BSR)。
LTE标准中，BSR分为长BSR(Long BSR)和短BSR(Short BSR)。当前时隙，若UE有多于一个逻辑信道组(英文：Logical Channel Group，简称：LCG)的数据需要传输，则发送长BSR；否则发送短BSR。长BSR中按照规定顺序给出每个LCG对应的表征数据量的值，例如：LCG 0/1/2/3分别对应100/200/300/400字节。该数据量为UE待发数据包的数据量，即1000字节。目前第三代合作伙伴计划(英文：The 3rd Generation Partnership Project，简称：3GPP)协议规定，BSR中包含4个LCG分别对应的待发数据量。短BSR中包含LCG标识(ID)以及对应的表征数据量的值。在具体实施过程中，表征数据量的值，具体可以是数据量的本身，例如：待发数据包为1000字节，那么在BSR携带的值即为1000。也可以是数据量对应的级别值。例如：1～10字节对应的级别值为1。10～12字节对应的级别值为2等。具体可以参见36.321协议的6.1.3.1-1和6.1.3.1-2表格。
或者蜂窝网接入设备接收到UE发送的增加是否分流标识的BSR，所述BSR除了上述必要信息外，额外增加是否分流的标识。例如用1bit作为是否分流的标识位，若值为1则表示需要分流，若值为0则表示不需要分流。
当蜂窝网接入设备接收到UE发送的BSR之后，就可以得知该UE是否有待发数据以及单个LCG或者多个LCG分别对应的待发数据的数据量。
如果通知信息为SR，那么蜂窝网接入设备即获知UE有上行业务数据需要发送。具体来说，可以采用现有蜂窝网中的机制来获取SR，例如每当UE的待发数据由无到有时，就会触发上报SR，那么对应的，蜂窝网接入设备，例如基站，就可以接收到SR。
当在步骤201中接收到通知信息之后，接下来执行步骤202，即根据通知信息确定UE是否有要进行业务分流的上行业务数据。
在具体实施过程中，步骤202可以具有多种实现方式，以下分别举例进行说明。
第一例：在步骤201中，蜂窝网接入设备接收的是UE发送的SR或BSR。那么在步骤202中可以自己决定是由自身调度UE，还是由AP调度UE；或者是自身和AP均调度该UE。若蜂窝网接入设备收到的是UE发送的BSR，则除了确定由谁调度所述UE之外，还需要eNB根据自身以及WLAN网络的负载、信道条件等，以及根据所述BSR确定多少待发数据分流到WLAN网络中。例如BSR中显示UE总待发数据量为1000bytes，eNB确定1000bytes全部分流到WLAN，或者500bytes分流到WLAN，剩下500bytes eNB自己调度。
第三例：蜂窝网接入设备接收UE发送的增加是否分流标识的BSR。为方便描述，增加是否分流标识的BSR称为第二BSR。当蜂窝网接入设备接收到增加是否分流标识的BSR，即可确定该UE有要进行业务分流的上行业务数据。
在本实施例中，第一BSR和第二BSR具体可以是不同类型的BSR。第二BSR可以沿用第一BSR的格式，即区分长BSR和短BSR，同时增加是否分流的标识位。也可以仅仅只包含UE标识以及该UE所有待分流的数据量。
在另一种可能的实施例中，UE同时发送2个第二BSR，两者通过是否分流标识位中不同的值来区分。标识位用于标识是否需要分流业务到WLAN。举例来说，BSR1的标识位的值为0，表示该BSR1表征的数据不需要分流到第一网络侧设备所处的网络，所以蜂窝网接入设备确定UE没有要进行业务分流的上行业务数据，并且蜂窝网接入设备可以根据BSR1调度该UE。BSR2的标识位的值为1，表示该BSR2表征的数据需要分流到WLAN进行发送，所以蜂窝网接入设备就确定UE有要进行业务分流的上行业务数据，并在步骤203中发送第一指示信息给AP。
可选的，当蜂窝网接入设备接收UE发送的第二BSR之前，该方法还包括：蜂窝网接入设备发送第三指示信息给所述UE，第三指示信息用于指示所述UE在WLAN AP发送所述要进行业务分流的上行业务数据；并指示所述UE设置第二BSR的标识位。
其中，该指示命令表示需要分流业务到WLAN，所以UE可以通过设置是否分流的标识位的值来通知蜂窝网接入设备哪个BSR所携带的数据量是要分流给WLAN的。
在实际运用中，指示命令可以包括分流的策略。具体可以通过广播或无线资源控制(英文：Radio Resource Control；简称：RRC)协议来通知UE。
第四例，在步骤201中接收到的通知信息包括是否分流的标识，所述是否分流的标识用于指示所述要传输的上行业务数据为所述要进行业务分流的上行业务数据。那么在步骤202中，蜂窝网接入设备通过检查通知信息是否包括是否分流的标识来确定是否有要分流的上行业务数据。
可选的，在步骤203中，蜂窝网接入设备可以单独的发送每个UE的第一指示信息给AP。但在实际运用中，也可以是同时将多个UE的第一指示信息在一个消息里发送。举例来说，当第一指示信息包括指示有数据和没有数据的指示时，蜂窝网接入设备将UE的标识和指示的位图(bitmap)的位置对应关系发送给第一网络侧设备。请参考表一所示。
UE1 UE2 UE3 UE4 UE5 UE6 UE7
表一
然后，蜂窝网接入设备根据UE的标识和指示的位图的位置对应关系，将多个UE的指示列表发送给第一网络侧设备。请参考表二所示，其中，指示用1比特来表示。
1 0 1 1 0 0 0
表二
当AP接收到表二的消息时，可获知UE1、UE3和UE4有上行数据要发送。
类似的，如果第一指示信息中包含数据量时，也可以是蜂窝网接入设备先将UE的标识和数据量位图的位置对应关系发送给第一网络侧设备，例如如表一所示。然后在步骤202中，将获得的多个UE的数据量列表发送给第一网络侧设备。请参考表三所示。
12 54 0 8 31 0 46
表三
在表三中，假设数据量由级别值来表征。假设共有64个级别，为0～63。0表示没有上行数据。其他级别具体可以参见36.321协议的6.1.3.1-1和6.1.3.1-2表格。则每个UE对应6个比特。当AP接收到表三的消息时，可获知UE1的数据量的级别为12，UE3和UE6没有上行业务数据要发送。
可选的，该方法还包括：蜂窝网接入设备向所述UE发送第三指示信息，第三指示信息用于指示所述UE在WLAN AP发送所述要进行业务分流的上行业务数据。
接下来请再参考图3所示，为本申请实施例中UE侧的上行业务数据传输的方法的流程图。该方法包括以下内容：
步骤301：UE接收WLAN AP根据从蜂窝网接入设备接收到的第一指示信息而发送的第二指示信息或蜂窝网接入设备发送的第三指示信息，其中，第一指示信息用于指示WLAN AP UE在WLAN AP有要进行业务分流的上行 业务数据或者指示WLAN AP要进行业务分流的上行业务数据的数据量，所述第二指示信息和所述第三指示信息均用于指示UE向WLAN AP发送要进行业务分流的上行业务数据；
步骤302：UE向WLAN AP发送要进行业务分流的上行业务数据。
本实施例中的第一指示信息、第二指示信息和第三指示信息与前述所描述的含义相同，所以在此不再赘述。
可选的，该方法还包括：UE向蜂窝网接入设备发送通知信息，通知信息用于通知蜂窝网接入设备UE有要传输上行业务数据，以使蜂窝网接入设备根据通知信息确定UE在WLAN AP有要进行业务分流的上行业务数据。
可选的，所述通知信息包含是否分流的标识，所述是否分流的标识用于指示所述要传输的上行业务数据为所述要进行业务分流的上行数据。
可选的，UE可以通过预定策略确定要进行业务分流的上行业务数据。预定策略可以有多种。例如：将60％的数据分配给WLAN，将40％的数据分配给蜂窝网。再例如：将第一业务例如网络协议电话(英文：Voice over Internet Protocol；简称：VoIP)产生的数据分配到蜂窝网，将第二业务例如视频业务产生的数据分配给WLAN。该预定策略具体可以是协议规定的，也可以是由UE决定。
为了更清楚的说明本申请实施例中的上行业务数据传输的方法的实施过程，以下分别举几个具体的例子来说明。
首先请参考图4所示，为本申请实施例中上行业务数据传输的方法的一个具体实例。其中，蜂窝网接入设备以蜂窝网中的基站为例。
首先，当UE有上行数据时，UE向基站上报SR，然后基站发送第一指示信息给接入点。接入点在接收到第一指示信息之后，获知UE有上行数据需要发送，然后向该UE发送第二指示信息以调度该UE。然后，UE基于第二指示信息向接入点发送上行业务数据。
请再参考图5所示，与图4不同的是，基站在接收到UE发送的SR之后，不发送给接入点，而是在等到接收到UE发送的第一BSR之后，eNB根据自 身以及WLAN网络的负载、信道条件等，以及根据所述BSR确定多少待发数据分流到WLAN网络中，即确定由接入点调度的第二数据量。基站将第二数据量携带在第一指示信息中，并发送给接入点。接入点在接收到该第一指示信息之后，向UE发送第二指示信息以开始调度UE。然后UE在接收到第二指示信息之后发送上行业务数据。
接下来请参考图6所示，在本实施例中，UE发送SR给基站。然后UE发送第二BSR给基站。基站在接收到第二BSR时，根据BSR中的标识位的值确定分流业务给接入点。基站就根据第二BSR中携带的数据量通过第一指示信息发送给接入点。接入点在接收到第一指示信息之后，向UE发送第二指示信息以开始调度UE。然后UE在接收到第二指示信息之后发送上行业务数据。
由以上描述可以看出，在本申请实施例中，在蜂窝网接入设备的辅助下，WLAN AP能够获知UE是否有上行业务数据要发送，从而对UE指示UE发送上行业务数据，避免了对没有上行数据的UE的调度，所以可以提高信道的利用率。
基于同一发明构思，本申请一实施例中还提供一种无线局域网接入点，图7所示的接入点涉及到的术语的含义以及具体实现，可以参考前述图1至图6以及实施例的相关描述。
请参考图7所示，该接入点包括：接收单元401，用于接收蜂窝网接入设备发送的第一指示信息，第一指示信息用于指示WLAN AP蜂窝网接入设备所服务的用户设备UE在WLAN AP有要进行业务分流的上行业务数据；发送单元402，用于根据第一指示信息向UE发送第二指示信息，第二指示信息用于指示UE向WLAN AP发送上行业务数据。
可选的，第一指示信息还用于通知WLAN APUE的标识信息，标识信息用于WLAN AP识别UE。
可选的，AP还包括：处理单元，用于启动定时器；并在定时器超时后，控制接收单元401停止从UE接收上行业务数据，并释放为UE发送上行业务 数据所分配的资源。
前述图1实施例中的上行业务数据传输的方法中的各种变化方式和具体实例同样适用于本实施例的接入点，通过前述对上行业务数据传输的方法的详细描述，本领域技术人员可以清楚的知道本实施例中接入点的实施方法，所以为了说明书的简洁，在此不再详述。
基于同一发明构思，本实施例还提供一种无线局域网接入点，图8所示的接入点涉及到的术语的含义以及具体实现，可以参考前述图1至图6以及实施例的相关描述。
请参考图8所示，为本实施例中接入点的硬件结构图。该接入点包括：接收器501，用于接收蜂窝网接入设备发送的第一指示信息，第一指示信息用于指示WLAN AP蜂窝网接入设备所服务的用户设备UE在WLAN AP有要进行业务分流的上行业务数据；发送器502，用于根据第一指示信息向UE发送第二指示信息，第二指示信息用于指示UE向WLAN AP发送上行业务数据。
